Risk factors for moderate acute malnutrition among children with acute diarrhoea in India and Tanzania: a secondary analysis of data from a randomized trial.

BACKGROUND: Moderate acute malnutrition (MAM) affects over 30 million children aged < 5 years worldwide. MAM may confer a greater risk of developing severe malnutrition and even mortality in children. Assessing risk factors for MAM may allow for earlier recognition of children at risk of deleterious health outcomes. OBJECTIVE: To determine risk factors associated with the prevalence and development of MAM among children aged 6 to 59 months with acute diarrhoea who received treatment with oral rehydration solution and zinc supplementation. METHODS: We conducted a secondary analysis of data from a randomized, dose-finding trial of zinc among children with acute diarrhoea in India and Tanzania. We used regression models to assess risk factors for prevalent MAM at the start of diarrhoea treatment and to identify risk factors associated with the development of MAM at 60 days. MAM was defined as weight for length (or height) Z score ≤-2 and > -3 or mid-upper arm circumference < 12.5 and ≥ 11.5 cm. RESULTS: A total of 4,500 children were enrolled; 593 (13.2%) had MAM at the baseline. MAM at baseline was significantly less common among children in Tanzania than in India (adjusted risk ratio [aRR] 0.37, 95% confidence interval [CI]: 0.30, 0.44, P < 0.001), in children aged 24- < 60 months versus 6- < 12 months (aRR 0.46, 95% CI: 0.38, 0.56, P < 0.001), and in families with household wealth index higher than the median (aRR 0.79, 95% CI: 0.68, 0.92, P = 0.002). Sixty days after outpatient treatment and follow-up, 87 (2.5%) children developed MAM. When compared to children aged 6- < 12 months, children aged 24- < 60 months had a 52% lower risk of developing MAM. Every one unit increase in weight for length (or height) Z score at enrolment was associated with a 93% lower risk of developing MAM during follow-up. CONCLUSIONS: Among children with diarrhoea, younger children and those from households with lower wealth were at greater risk of MAM. These children may benefit from targeted interventions focusing on feeding (targeted nutrition support for at-risk households) and follow up in order to reduce the occurrence of MAM and its consequences.

Risk factors for mortality among Tanzanian infants and children.

BACKGROUND: During the era of the Millennium Development Goals, under 5 mortality rates decreased significantly worldwide; however, reductions were not equally distributed. Children in sub-Saharan Africa still account for more than 50% of the world's annual childhood deaths among children under 5 years of age. Understanding upstream risk factors for mortality among children may reduce the large burden of childhood mortality in sub-Saharan Africa. Our objective was to identify risk factors for mortality among infants and children in Tanzania. METHODS: We conducted a secondary analysis of data pooled from two randomized-controlled micronutrient supplementation trials. A total of 4787 infants were enrolled in the two trials (n = 2387 HIV-exposed and n = 2400 HIV-unexposed). Predictors of mortality were assessed using unadjusted and adjusted hazard ratios (aHRs). RESULTS: There were 307 total deaths, 262 (11%) among children who were HIV-exposed and 45 (2%) among children who were HIV-unexposed (P < 0.001). The most common cause of death was respiratory diseases (n = 109, 35.5%). Causes of death did not significantly differ between HIV-exposed and HIV-unexposed children. In adjusted regression analyses, children with birth weight <2500 g (aHR 1.75, 95% CI 1.21-2.54), Apgar score of ≤7 at 5 min (aHR 2.16, 95% CI 1.29-3.62), or who were HIV-exposed but not infected (aHR 3.35, 95% CI 2.12-5.28) or HIV-infected (aHR 27.56, 95% CI 17.43-43.58) had greater risk of mortality. CONCLUSIONS: Infection with HIV, low birthweight, or low Apgar scores were associated with higher mortality risk. Early identification and modification of determinants of mortality among infants and children may be the first step to reducing such deaths.

Reasons for Interfacility Emergency Department Transfer and Care at the Receiving Facility.

OBJECTIVES: The aims of this study were to (1) assess the reasons for pediatric interfacility transfers as identified by transferring providers and review the emergency medical care delivered at the receiving facilities and (2) investigate the emergency department (ED) care among the subpopulation of patients discharged from the receiving facility. METHODS: We performed a multicenter, cross-sectional survey of ED medical providers transferring patients younger than 18 years to 1 of 4 US tertiary care pediatric hospitals with a subsequent medical record review at the receiving facility. Referring providers completed surveys detailing reasons for transfer. RESULTS: Eight hundred thirty-nine surveys were completed by 641 providers for 25 months. The median patient age was 5.7 years. Sixty-two percent of the patients required admission. The most common reasons for transfer as cited by referring providers were subspecialist consultation (62%) and admission to a pediatric inpatient (17%) or intensive care (6%) unit. For discharged patients, plain radiography (26%) and ultrasonography (12%) were the most common radiologic studies. Procedural sedation (16%) was the most common ED procedure for discharged patients, and 55% had a subspecialist consult at the receiving facility. Ten percent of interfacility transfers did not require subspecialty consult, ED procedure, radiologic study, or admission. CONCLUSIONS: Approximately 4 of 10 interfacility transfers are discharged by the receiving facility, suggesting an opportunity to provide more comprehensive care at referring facilities. On the basis of the care provided at the receiving facility, potential interventions might include increased subspecialty access and developing both ultrasound and sedation capabilities.

Diagnostic approach to constipation impacts pediatric emergency department disposition.

OBJECTIVES: Constipation is a common cause of abdominal pain in children presenting to the emergency department (ED). The objectives of this study were to determine the diagnostic evaluation undertaken for constipation and to assess the association of the evaluation with final ED disposition. METHODS: A retrospective chart review of children presenting to the pediatric ED of a quaternary care children's hospital with abdominal pain that received a soap suds enema therapy. RESULTS: A total of 512 children were included, 270 (52.7%) were female, and the median age was 8.0 (IQR: 4.0-11.0). One hundred and thirty eight patients (27%) had a digital rectal exam (DRE), 120 (22.8%) had bloodwork performed, 218 (43%) had urinalysis obtained, 397 (77.5%) had abdominal radiographs, 120 (23.4%) had abdominal ultrasounds, and 18 (3.5%) had computed tomography scans. Children who had a DRE had a younger median age (6.0, IQR: 3.0-9.25 vs. 8.0, IQR: 4.0-12.0; p<0.001) and were significantly less likely to have radiologic imaging (OR=0.50, 95% CI 0.32-0.78; p=0.002), but did not have an increased odds of being discharged home. After adjusting for gender, ethnicity, and significant past medical history those with an abdominal radiograph were less likely to be discharged to home (aOR=0.56, 95% CI 0.31-1.01; p=0.05). CONCLUSIONS: The diagnostic evaluation of children diagnosed with fecal impaction in the ED varied. Abdominal imaging may be avoided if children receive a DRE. When children presenting to the ED with abdominal pain had an abdominal radiograph, they were more likely to be admitted.
